GOT A QUESTION FOR YOU GUYS. I TOOK THE NEW TWIN MERCURY 250 VERADOS OUT FOR A RIDE TODAY. APPROX 61 MILES, THE WEATHER WAS SLOPY TO DOWN RIGHT SNOTTY! I BURNED 80 GAL OF FULE. CAN THE PROPS MAKE THAT MUCH OF A DIFFERENCE. I HAVE DEALER ISSUED 4 BLADE ALUMINUM PROPS ON RIGHT NOW. I'M SUPPOSED TO GET THE NEW THREE BLADE INIRITA PROPS. THEY ARE STRONGER, THINNER AND SHARPER THAN THE STAINLESS STEEL PROPS OF TODAY. THANKS TOM...KEY-LIME-PIE

if the props are wrong,everything will be effected...here's the correct way to prop a boat...
get the boat into the condition in which it's normally ran-example,full fuel,enclosure down,and the extra weight of people and beer...take the boat out for a ride,open the throttle,read what the top rpm you see is...compare that number with the engine mfg's reccomended rpm range...you want to be at the top rpm or slightly over it-slightly is 100rpm max !!!
here's where it gets tricky...
with outboard boats,the more the hull is out of the water the more the rpm will climb...general guide line is 150rpm for every inch of pitch....propping the boat in this manner will allow the boat to plane at a lower rpm,it will also reduce time to plane and the load on the engine is less,meaning you WILL burn less fuel....
side note....
i wouldn't use black dog for prop repairs on a bet-i had a terrible experience with them...
the only prop shop i reccomend is eastern prop in seaville nj-i use their services for my customers-NEVER had a problem...
